Very satisfied with product. Its powerful. After trying it sucks black dots very well. Small advise. Do this after you wash and take a warm glove on your nose. It's more effective

Haylou Bluetooth Earphones Packed well. After charging they ran for straight 3 hours which is longer than stated.After sitting in case they were good to go again.The range seems to be about 40 feet or so. I'm very happy with the quality of the sound. This was a great value
